Got F40 error code self-cleaning my 790.9642 Kenmore range
Got an F40 error code at the end of self-cleaning my Kenmore range. Reset the alarm....a few minutes later it came up again and reset again. The cooktop/door eventually unlocked, but the error concerns me.The range appears to be working fine otherwise.

Re: Got F40 error code self-cleaning my 790.9642 Kenmore...
after several calls I finally found out what the code meant. code meant. Power supply issues, not necessarily with your power supply but with the appliance itself. Of course they want to send a technician for $65.00, which may be worth the headache. All someone told me was to turn off the power braker for 2 hours and try again. Yeah right, after 2 hours of heating your house and paying the electric bill, but when breaker is off there will not be any electric used. code f40,

it is a cooktop lockout error and usually occurs after or during the oven self clean process. If this is the case then let the oven cool down after self clean and see if it goes away. Most likely the wiring harness containing the signals from sensor to the control module is damaged. If it persists you will need to get a technician in.
The "F40" fault code indicates a Cooktop Lockout error. There is a "Lockout" control board that locks out the cooktop from operating whenever the "Clean" cycle is used. It's not normal to display "F40" unless there is a "Lockout" or an "EOC" (electronic oven control) failure. It may need one or the other or both boards replaced. If the cooktop will operate after the range has cooled and unlocked then it may need the EOC and not the Lockout board. If you can ignore the beeping and the F40 and the range will heat up again in the clean cycle and complete the clean cycle then it could have a faulty Lockout board. Here a link to a YouTube video with the instructionson how to access and replace the EOC.
Typically this means the cycle is completed or there is an error detected. Reset the unit at the household circuit breaker fora bout 10 minutes, then retry the unit. Let me know if this happens again. Also let me know if you see any alpha-numeric error codes.
The control (TIMER) has likely failed in this instance - BUT...
Sometimes when you disconnect power to a range and reconnect it the electronic range control gets confused. You should disconnect power again for 15 seconds and reconnect and see if that helps.
If it doesn't cure the E1- F5 error hold the bake button in until E0- F2 appears in the display. This is the error for a stuck button on the keypad and is the way to clear the memory of the electronic range control.
Sometimes these work, but if the control has failed it won't make any difference.

My experience (Kenmore Ultra-bake Model 665-72002102) was that E1 F5 meant an error with the oven lock switch. In our case, the latch was partly stuck from food or other debris. Just moving the latch back and forth loosened the scale that was making it stick, and it worked again.
My oven will not work. After pressing the desired temp on the oven, the preheat light and oven light comes on. After about 15 minutes, the oven is slightly warm and maybe an hour later the oven may or may not heat to desired temp. Kenmore gas range model #790.72851301.
